• create and display a score of how well the buns are positioned based on their final position. The stats can also include the number of bun movement, time used, and so forth.
• How accurate is 3D eye-tracking? (maybe this can be implemented as a separate base package)
• System error: Hand in the baking tray change to controller when turning them on/off. This a Steam VR artefact. It assigns left/right based on position relative to the HMD. Solution: update Unity and Steam VR?
• Reset bun position
• Confused when losing the buns on the table, wants to leave the hand on the table, move the wheelchair, lean into the table.

Right now we are running into trouble in data analysis because it is difficult to distinguish tests performed with baking tray from each other.

• Make it possible in UI to set a test number.
• Log the test number so we can distinguish tests from each other, when several are performed for the same participants.

• The scene currently doesn't have nice lighting, and lack more or less shadows completely.
• The current model does not look like something eatable, so it would be nice to have a proper cookie model instead.

For head_ori_x,y,z we cannot use the quaternion coordinates (transform.rotation.x etc), it would be better to the rotation in terms of euler angles, ie. (transform.eulerAngles.x etc.). Should be fixed in LoggerBehavior.cs. See also med-material/MuseumKitchenTaskVR#7

• Document the expected logging format - explanations of what the individual variables are supposed to log.
• Test that the individual variables actually log as intended.

Currently the buns are logged from their individual world space position. However, since we perform a calibration for each participant, this effectively makes it hard to compare the bun positions to each other (see picture below).

Instead I suggest:

• Retreive the HMD position at the point in time of calibration and store it for the rest of the test.
• Stop calibrating Scene based on head rotation, it should only be based on head position.
• Implement a new column in LoggerBehavior+AppConstants, which subtracts the HMD position from the last_bun world position.
• Alternatively, Implement a column which logs last_bun.transform.localPosition which will log its position relative to its parent (which will only change if the user manipulates with the bun).

Currently the Baking tray task uses soft yellow spheres to indicate cookies. Instead we should use the cookie model designed by @EkatiSag as seen below
